J8 SWITCHES WITH
TRIP FUNCTION
UPGRADED TYPE
POWER ROCKER SWITCH
FEATURES
1. Power switches with an electromag-
netic reset function which meet the
need for energy savings in equipment
and for safety.
Applications for these switches include
promoting energy savings in equipment
(by reducing power consumption when
OA equipment is in standby mode, for
example), preventing fires caused by
overheating of a heater inside equipment,
preventing electrical leaks, and automati-
cally turning off the power if the unit tips
over or is shaken. These switches feature
a built-in electromagnetic reset function
that shuts off the main power supply in
response to a signal that is received from
an external sensor.
2. A dramatic upgrade in operation
feelings
These switches provide the same
comfortable operation feelings our
conventional J8 switches.
• Comparison of feel when switch is
turned on
3. CT terminals adopted for coil termi-
nals
These switches can be used with AMP's
CT connectors, which are widely used for
wiring connections in OA equipment,
making it possible to achieve greater effi-
ciency in wiring work.

4. Prolonged electrical service life.
Coil operation provides an electrical life
of at least 50,000 switching operations.
5. Assures excellent ability to with-
stand inrush current when used to
turn a power supply on/off.
The switch uses our own proprietary
mechanism that provides an excellent
ability to withstand inrush current is
employed.
Inrush current rating (IEC65) : 160A (nor-
mally 16A at 125V AC), 10,000 times
6. Approved under major international
safety standards.
UL, cUL, TÜV and SEMKO approved.

NOTES
1. Operating voltage application time
If the rated voltage is applied to the coil
for more than 10 seconds or the maxi-
mum voltage is applied for more than 1
second, coil performance may deterio-
rate.
2. The shape of the mounting panel
should be as recommended in the
dimensions diagram.
Contact us if you are considering using a
panel of other than the recommended
size and shape.
3. The mounting panel should be made
of SPCC. If a different material is used,
its adhesion to the switch unit may be
not be as strong. Check this on site if
necessary.
4. Note that the actuator could pop out
of the switch housing if 19.6N (2kgf) or
more of force is applied to the side of
the actuator.
5.
(1) When connecting the tab terminals,
use a .250 receptacle and insert the ter-
minals straight in.
If you insert them at an angle, the termi-
nals could catch on the opening and will
require greater insertion force.
(2) The coil terminals have specific polar-
ities. Make sure you connect them cor-
rectly.
(3) Use a receptacle that is compliant
with JIS C 2809.
In addition, there is some deviation
regarding the insertion force depending
on the model used from different manu-
facturers, so the insertion force should be
checked under realistic conditions.
(4) Use AMP's CT connector for the coil
terminals.
6. Because special receptacle termi-
nals are used for the contact terminals
and the common terminals, do not
attempt to solder them. Doing so
could melt plastic components and
otherwise harm the performance of
the switch
7. The terminals should be connected
in such a way that they are not under
constant stress from the connecting
wires.
8. Take care not to drop the product as
it may impair performance.
9. Resistance to chemicals
To clean the switch unit, use a neutral
detergent diluted with water.
Do not use acidic or alkaline solvents as
they may damage the switch.
Furthermore, be careful not to get any of
the detergent solution inside of the switch
while cleaning it.
10. This product is not hermetically
sealed, so its performance could dete-
riorate under certain ambient condi-
tions. Avoid using and storing these
switches in a location where they will
be exposed to corrosive gases, sili-
con, or high dust levels, all of which
can have an adverse effect on the con-
tacts. In addition, because these
switches contain permanent magnets,
avoid using and storing these
switches in a location where metallic
dust, etc., is present.
11. When these switches are used with
weak currents of 500mA or less, a
layer of material on the surface of the
contacts may cause contact instabil-
ity. Check and evaluate this possibility
before using these switches under
such conditions.
12. When using an ON-OFF type
switch with no (|O) indication on the
actuator, the "OFF" position should be
indicated on the set in which the
switch is installed.
13. To assure reliability, check the
switch under actual loading condi-
tions. Avoid any situation that may
adversely affect switching perfor-
mance.
COIL TERMINAL CONNECTOR
Because CT terminals are used for the
coil terminals, AMP's CT connector can
be used.
Remark: We do not sell this type of connector.
Questions concerning this connector
should be directed to the manufac-
turer.
